In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

This commit fixes macros used to create named-fans instances.
It will enable to have multiple named-fans declared in devicetree
without raising "multiple definitions" error during compilation.
BRANCH=main
BUG=none
TEST=Add named-fans instance in device tree and build firmware.
Compilation with 2 or more names-fans should work correctly.

Add fan support to Zephyr. The fan is controlled with PWM and the fan
speed is measured with the tachometer. Fan properties are defied in the
dts file. The struct fan_t fans[] array and enum fan_channel are
generated automatically according to named-fans node in the device tree.
The implementation is based on the npxc driver, but it is
platform-independent. It assumes that there are PWM channel to control
the fan and the tachometer sensor to measure RPM (in RPM mode). If it is
not the case in the future, the shim may be split per chip.
Enable fan related console commands - fanduty, fanset, faninfo, fanauto
and host commands - EC_CMD_PWM_GET_FAN_TARGET_RPM,
EC_CMD_PWM_SET_FAN_TARGET_RPM, EC_CMD_PWM_SET_FAN_DUTY,
EC_CMD_THERMAL_AUTO_FAN_CTRL.
BUG=b:174851463
BRANCH=none
TEST=build Zephyr
TEST=Run "fanset"/"fanduty" commands and check with "faninfo" if the fan
follows the command. Then run "fanauto" and verify that the fan controls
the temperature correctly.
